Abstract
A molding apparatus defining a processing direction includes multiple molding modules spaced apart in a lateral direction perpendicular to the processing direction and a common reaction surface. Each molding module includes a frame and a mold roll that defines molding cavities. Each mold roll defines a respective pressure zone in cooperation with the reaction surface and each mold roll is movable with respect to the reaction surface by controlled operation of the frame. Molten resin is introduced into the pressure zones and forced into the molding cavities to form arrays of fastener elements extending from base layers of resin formed on the surfaces of the mold rolls. The fastener elements are withdrawn from the cavities while stripping the base layers from the peripheral surfaces.
